Application :filed April 8, 1910. Serial N o. 554,310.

To all whom it may concern:

Be it known that I, EUCLIDE EUGENE LEPINE, resident of the town of Joliette, in the Province. of Quebec, inthe Dominion of Canada, a subject of the King of Great Britain, have invented Certain new and useful Improvements in Lime-Hydrating Machines; and Iv do hereby declare that the following is a full, clear, and exact description of the same.

The invention relates toimprovements in lime hydrating machines, as described in the present specifica-tion and illustrated in f the accompanying drawings that form part of the same.

The invention consists essentially in the novel arrangement and construction of parts whereby the lime, deposited on a moving platform, receives `a definite quantity of water and the continuity of the process maintained during the operation of the machine.

The objects of the invention are to provide a machine, which will much facilitate the operation of slaking lime and minimize crystallization, to devise a structure wherein the parts and the arrangement are very simple, therefore easy to maintain and cheap to manufacture, as Well as being of durable form, and generally to furnish a means of increasing the value of the product at a minimum expense of production.

ln the drawings` Figure 1 is a 'sectional side elevation of thel machine. Fig. 2 is a plan View of the machine partly in section on the line A-B in Fig. 1. Fig. 3 is a cross sectional view of the machine on the line (l-D in Fig. 1. view en the line E-F in Fig. 1.

Referring to the drawings, 1 is the main casing of the machine, of a box like form having the'lfeed opening 2 adjacent to its upper 'end and the slot 3 extending across the upper end wall 4 adjacent to the bottom 5 of said casing and the slot 6 extending across Land 4through the inner Wall 7 of the enlarged end S of the casing, said enlarged end preferably having the curved wall 9 extending'downwardly below said enlarged end to the conveyer chamber 10, said casing also has the pipe opening 11 intermediate of its length, the armholes 12 and l'and the bearings 14 in thesides thereof at the said enlarged end,- the extension from said enlarged end of the chamber,'viz,p-the con- Fig. 4 is a cross sectionalv veyer chamber 10 having also bearings 15 in. the side walls thereof.

the feed vopening 2 has a steam exhaust opening 16 across.

17 is the base of a frame. 18 are the uprights of said frame shown as suitably braced from said base by the braces 19 and 20, said frame supports the casing 1 in an inclined position, the uprights 18 ,intermediate of the length of said casing and at the feed portiony of said casing being of greater height than the uprights at lthe discharge end of the casing.

21 isa hopper extending completely across the top of the casing l over' the feed opening 2.

22 is a shaft longitudinally vgrooved to form channels and journaled in the hopper walls at the entrance from said hopper to the main casing 1, in otherV .words at the feed opening 2, said shaft extends slightly beyond oneside of said casing. 23 is a pulley mounted on t-he shaft 22 outside of said casingl and suitably driven.

24 is an exhaust chamber over the opening 16 leading to the steam exhaust pipe 25.

26 is a slide valve havingthe ports 2T extending completely thereand operated by the lever 28, said lever besaid wall 3()c terminating intermediateof 100 thedepth ofthe interiorof the casing.

30d are inclined Walls longitudinally arranged within the casing 1 extending from end to end thereof.

31 is a water pipe suitably connected to a 105 Water supply and extending along above the lower end of the maincasing 1 and leading into saidv casing through the pipe opening 11 and along under the top of said casing andthrough` a second pipe opening above 110` said feed .hopper and again through said casing to the spraying pipe 32, said pipe 32 extending across the casing between the openings 2 and 16, sothat the lime Will receive itscharge of Water at once vbeforestarting on its travel through said casing.

33 isl a valve or cock in the Water pipe extending above 'the casing at the'upper end thereof for regulating the supply. f

.34 are rollers journaled in suitable bearing blocks 35 secured to the bottom of the casing 1 in the interior thereof at intervals throughout the length of said casing.

36 is a roll supported by theshaft 37, the latter being journaled in the bearings 14.

38 is a roll supported on the shaft 39, the latter being journaled in suitable bearings suitably supported just -beyond the upper end 'of the casing 1. L i

40 is a sheet of suitable material, such as sheet iron extending through the slots-3 and 6 and around therolls 36 and 38 in the form of a belt or moving platform, so that a portion of said platform is'alvvays Within the casing 1, in order that it may carry the lime 44 is a pulley mountedon the shaft 43 and `suitably driven, consequently it will be seen thatthe Worm 42, coactingwvith the Worm Wheel, 41, operates the moving platform 40. 'i 4,5visa screw conveyer journaled in the bearings 15 `in conveyer chamber 10.

46 is a pulley mounted on 'the 'extending .end ofthe shaft of the `screw conveyer 45 and suitably driven. u

In-theoperation of this machine, thellime is. fed vinto the hopper 21 and the water turned on, so that a predetermined `quantity will only {ioivv into'the spraying pipe 32. The machine is set-in motion and the vshaft 22 deposits. from one of its pockets a certain quantityof. lime von to the moving platform40, the Water' from the conveying pipe sprays ab'ovethe lmoving platform and on to this deposit of lime, then the slaling of the latter begins.

i v.- The continuous operation of the shaft 22 `and the .continuous travel ofthe platform,

as .Wellasthe constant operation of lthe Waterspray keep the process of slaking n1 continuous progress, While themachine is in motion and it Willv be -understood that the v heat'generatedfrom the li'me in its contact I The slaking of the line traveling-down the vmoving platform 40v is completed lfy the time it reaches the roll 36 and it is there dethrough a suitable discharge opening in the side of the casing 1.

The Water pipe i as extending through the casing and along under the top thereof, but this, of course is unimportant lexcept perhaps in cold countries, where it is advisable to have the Water heated forslaking` purposes. V

- It must lbe understood that Withoutdeparting from the spirit of this invention, the constructionof the various parts may be modified considerably in order to suit different conditions, the salient features of theinvention 'being the. moving plat-form and the feeding of the W'ater'to the lime and consequently the continuity of the process during the travel of said platform.

It'mav be here stated that this must not be confused with any. known machines in which various receptacles are used, because in the present invention, it is thel distribution of the lime a-nd thevvater on a surface, which is so important and very essential in obtaining the proper product.

The moving platform 40 within the casing moves immediately under the longitudinal inclined side Walls 301, so thatthe lime thereo n cannot be-deposited in passage over thel side edges ofsaid platform, but the cross directing the steam, generating in the main portion of the casing, tothe slide valve, in other Words, the wall 30c forms a barrier, thus the channels or grooves in the shaft 22 will not become clogged with Wet lime. AnyA steam there may be in the upper part of the casing beyond said Walll 30c will find egress through the openings 30h.

The arrangements for heating the water are `very sim le and that fact must be mentioned, but t is part of the invention is not essential in the operation o f the' machine.
